What Is SEO Content Writing?

SEO writing is the process of creating and publishing content while keeping in mind a user’s search intent. And it takes a lot of effort to curate top-notch content that focuses on the user’s needs versus generating fluff.

If your page content is useful, Google will most likely rank it for that particular keyword. For instance, say a consumer wants to buy a shower head, but the search is specific to the size of the bathroom.

Basing an article on the keyword “buy a shower head” will only sound commercial with little to no relevance. Now an article based on the keyword, “what size of shower head is best for small bathrooms,” has clear informative intent.

The end goal of SEO writing is to rank on the first page of Google’s search results. The search engine only picks up what it determines is relevant to a user’s search query.
